Plaque on Kids' Teeth: How to Get Plaque Off Kids’ Teeth

Plaque is as persistent a problem for children as it is adults - if not more so! That sticky, colorless film, better known as “fuzzy teeth,” can form within hours of brushing and turns into tartar if not addressed swiftly. That’s where a lot of real oral health complications begin.

Don’t worry, we’ll show you how to get plaque off kids’ teeth in this guide. It’s as simple as better brushing technique/frequency, using a mouthwash, teaching them how to floss, and potentially making some dietary changes. Even just encouraging them to rinse after eating helps.

The BEST defense against plaque on kids’ teeth, though, is LIVFRESH Kids+ Toothpaste. It features patented Activated Edathamil to dissolve plaque at the molecular level, removing it 250% better than leading brands in a bubble gum gel kids will actually use. 

Key Takeaways

  • Plaque buildup on kids’ teeth can harden into tartar, which can only be removed at the dentist.
  • Plaque forms on teeth within 4-12 hours of brushing. Twice-daily brushing is non-negotiable.
  • A better toothpaste that loosens plaque’s grip on the tooth surface makes a world of difference.
  • Other strategies include rinsing after eating/drinking, flossing, mouthwash, and dietary changes. 

What is Plaque, and Why is it a Problem?

Most oral health concerns can be traced back to plaque - the sticky, soft biofilm that forms on and between teeth as well as along the gum line. It’s made up of bacteria, food particles, and saliva. It constantly coats the teeth. 

The bacteria in plaque make acids that attack tooth enamel every time your child eats or drinks anything with sugar or starch - which, unfortunately, is most of what kids these days eat/drink. Those acid attacks can cause damage quickly on baby teeth since they have thinner enamel. But it’s a problem even adults face. Especially if you don’t remove that plaque fast enough.

The Tartar Transformation

Plaque on kids’ teeth is easy to remove. Tartar is another story. This is what you get when plaque is left on the tooth surface for 24-72 hours. The softer biofilm hardens into a yellowish, calcified substance that bonds so firmly to enamel that you can’t merely brush it away. You certainly can’t rinse it away. It requires professional dental cleaning. 

It’s a vicious cycle, too. Tartar creates a rougher surface that attracts more and more plaque. This is why figuring out how to get plaque off kids’ teeth is so important. 

Identifying Plaque Buildup on Kids' Teeth

It’s hard to actually see plaque buildup on kids’ teeth. That’s why it’s notorious for sneaking up on parents. Here are a few signs your child has plaque buildup:

  • They talk about a fuzzy or rough feeling on their teeth, especially around the gum line
  • Yellowish or white deposits near the base of the teeth
  • Gums look red, puffy, or bleed during brushing
  • Constant bad breath even after brushing 

Honestly, it’s safe to assume your little one has plaque on their teeth right now. So, let’s get into how to remove plaque from kids’ teeth below! 

How to Get Plaque Off Kids’ Teeth

You know most of this advice on managing plaque on kids' teeth already - rinse, brush, floss, use a mouthwash, and get regular dental checkups. But a little refresher on proper technique never hurt! 

Brushing Technique and Frequency

The bare minimum is twice a day, every day, for two minutes at a time. You should get your child a sand timer and show them how to use it. Make it a game. Maybe even brush alongside them so you can make sure they are cementing the habit.

Technique is important, too. The bristles should be angled at 45 degrees toward the gum line. Use short, gentle strokes. You will be the one doing the brushing until your child is around the age of 5-6. Or, at least supervise if your little one is passionate about doing it themselves.

Most children miss the back molars and the tongue-side surfaces of the front lower teeth. That’s where you’ll see most plaque buildup on kids’ teeth. So encourage them to get all the little nooks and crannies.

Plaque-Removal Toothpaste

If you only take away one thing from our guide on how to get plaque off kids’ teeth, it should be this. Basic drugstore formulas don’t cut it. Especially the gentle kids toothpastes. 

LIVFRESH Kids+ Dental Gel has an ingredient backed by 40 patents and 40 clinical studies showing it can remove plaque up to 250% better than a leading ADA alternative. The difference is in how it alters the surface charge of the tooth, making it harder for plaque to hang on. 

It’s one of the best dentist-recommended toothpaste formulas for children because it contains no fluoride, SLS, or other toxic chemicals. It’s 100% safe to swallow. Your child will love the pink bubblegum flavor, too!

When Does a Mouthwash Make Sense?

LIVFRESH also has a plaque-removing mouthwash featuring the same Activated Edathamil ingredient that makes the toothpaste so powerful. But what age is a mouthwash safe for children?

Most dentists recommend waiting until age 6 when you can trust your child to swish and spit without swallowing. At this point in time, a good rinse helps reach all the spots that the toothbrush bristles missed. It’s one of the best pieces of advice we have to offer on how to remove plaque on teeth at home.

Flossing Can’t Be Overlooked

Plaque loves to work its way between teeth where bristles can’t reach. That’s why flossing should begin once your child has two teeth that touch. Floss picks are usually a better option for kids. Once-a-day flossing is a must.

Regular Dentist Visits Are Non-Negotiable

Some plaque is inevitably going to harden into tartar even with perfect oral care at home. You should schedule professional cleanings every six months to remove what home care misses. This is also an opportunity for your child’s dentist to spot early signs of decay, apply sealants to molars, and give you an honest read on the state of your kiddo’s oral health.

Prevention is the Best Medicine For Plaque on Kids' Teeth!

It’s less about eliminating plaque on kids’ teeth and more about figuring out how to prevent plaque build-up. Because think back to what we talked about earlier - how long does it take for plaque to form on teeth? Just 4-12 hours!

Encourage your child to rinse with water right after eating or drinking anything. This will help offset early plaque formation. But keeping them on track with their oral health regimen is the best way to handle plaque on kids’ teeth. Set them up for success today!
